BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Carnation plant, botanically known as Dianthus caryophyllus, grown commercially as a container plant and hereinafter referred to by the name ‘Hilbeakate’.

The new Carnation plant is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program is to create new container Carnation plants with numerous flat flowers with a single whorl of petals.

The new Carnation plant originated from a cross-pollination made by the Inventor in De Kwakel, The Netherlands in June, 2010 of Dianthus caryophyllus ‘Kahori’, not patented, as the female, or seed, parent with a proprietary selection of Dianthus caryophyllus identified as code number A66180-03, not patented, as the male, or pollen, parent. The new Carnation plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in De Kwakel, The Netherlands in September, 2011.

Asexual reproduction of the new Carnation plant by terminal cuttings propagated in a controlled greenhouse environment in De Kwakel, The Netherlands since October, 2011 has shown that the unique features of this new Carnation plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Carnation have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Hilbeakate’. These characteristics in combination distinguish ‘Hilbeakate’ as a new and distinct Carnation plant:

-   -   1. Compact, uniformly mounding and upright to broadly spreading         plant habit.     -   2. Relatively small leaves.     -   3. Freely flowering habit.     -   4. Flat red purple-colored flowers with a single whorl of         petals.     -   5. Good container performance.

Plants of the new Carnation differ from plants of the female parent, ‘Kahori’ , in the following characteristics:

-   -   1. Plants of the new Carnation have larger flowers than plants         of ‘Kahori’.     -   2. Plants of the new Carnation have longer peduncles than plants         of ‘Kahori’.     -   3. Flower petals of plants of the new Carnation are red purple         in color whereas flower petals of plants of ‘Kahori’ are dark         pink purple in color.

Plants of the new Carnation differ from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Carnation have single-type flowers whereas         plants of the male parent selection have semi-double flowers.     -   2. Flower petals of plants of the new Carnation are red purple         in color whereas flower petals of plants of the male parent         selection are darker red purple in color.

Plants of the new Carnation can be compared to plants of Dianthus caryophyllus ‘Hilbeanaom’, disclosed in U.S. Plant patent application Ser. No. 14/545,367. Plants of the new Carnation differ primarily from plants of ‘Hilbeanaom’ in flower color as plants of the new Carnation have darker red purple-colored flowers than plants of ‘Hilbeanaom’.

Plants of the new Carnation can also be compared to plants of Dianthus caryophyllus ‘Twinkle’, not patented. In side-by-side comparisons, plants of the new Carnation differed primarily from plants of ‘Twinkle’ in the following characteristics:

-   -   1. Plants of the new Carnation had larger flowers than plants of         ‘Twinkle’.     -   2. Flower petals of plants of the new Carnation were red purple         in color whereas flower petals of plants of ‘Twinkle’ were red         in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Carnation plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Carnation plant.

The photograph comprises a side perspective view of a typical flowering plant of ‘Hilbeakate’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photograph and following observations and measurements were grown during the winter in 10.5-cm containers in a glass-covered greenhouse in De Kwakel, The Netherlands and under cultural practices typical of commercial container Carnation production. During the production of the plants, day temperatures ranged from 12° C. to 15° C., night temperatures averaged 12° C. and light levels averaged 7,000 lux. Plants were pinched one time five weeks after planting. Plants used for the photograph and description were 20 weeks old. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
